List of identities in trigonometry
WebTrigonometry has been noted for its many identities, that is, equations that are true for all possible inputs. Identities involving only angles are known as trigonometric identities. … WebThe three fundamental identities of trigonometry: sin 2 ( θ) + cos 2 ( θ) = 1 tan 2 ( θ) + 1 = sec 2 ( θ) cot 2 ( θ) + 1 = csc 2 ( θ) You can prove them by yourself just substituting the meaning for a triangle (, and ). For the last, I give to you, this representation of every trigonometric ratio:
